Below is a formula I want to use in conditional formatting. Its purpose is to blur a range in a text concatenation table if a checkbox B15 is unchecked and if the left and right of the string matches any value from 'Code Sheet'!X4:AD4 (m, ɱ, n, ɳ, ɲ, ŋ, or ɴ).
=iferror(and($B$15=false, if(match(left(C19,1),{'Code Sheet'!X4:AD4},0),if(match(right(C19,1),{'Code Sheet'!X4:AD4},0),true,false))),false)Any combo of the aforementioned values should be blurred by the conditional formatting. But my formula does not work outside of a cell. The conditional formatting box simply turns red without feedback. I have no idea why. Where am I going wrong?
Note: the concatenation table has the range of C19:CH102, and the table filters and transposes values - meaning the formula must also adapt to changes in data position.
P.S. Thanks Stack Exchange users for teaching me the ways of the spreadsheet. I'm on my way to becoming a spreadsheet wizard!
